Abstract
A marker deployment tool may comprise a marker cannula having a lateral deployment aperture, a push rod slidably disposed within the marker cannula and a scalloped tip coupled to the distal end of the marker cannula. The scalloped tip may have a push rod recess configured to receive a portion of the distal end of the push rod such that the push rod does not appreciably extend out of the lateral deployment aperture when the push rod is actuated distally. The marker deployment tool may further comprise a magnet at or near the distal end. This magnet may be used in combination with a magnet or plurality of magnets disposed about an access chamber in a tissue sample holder to assist the user in aligning the marker deployment tool. The access chamber in the tissue sample holder may also include a valve, two valves, or a removable plug.
